The city of New Orleans issued a boil water advisory on Wednesday (Dec. 18) for residents and businesses in the Venetian Isles area after a water main break, officials said.

After a water main break caused by a contractor, people living in Genoa, Murano, Alba, Francesco, San Marco, Naples, Fort McComb, Veronese, Burton, Palm Villa Marina and Lucrino are being asked to heat water before consuming it, according to officials.

The New Orleans Sewerage & Water Board, in conjunction with the Louisiana Department of Health and Hospitals (DHH), issued the precautionary boil water advisory. It will be in effect until further notice.

The Sewage & Water Board is recommending that residents disinfect their water by boiling it for one minute, then letting it cool down before consumption. The water board said it will notify residents when the advisory is lifted.
